#include <iostream.h> using namespace std; 然后编译时出现 error C2871: 'std' : does not exist or is not a namespace 查了一下,原来 C++有两个不同版本的头文件。引入名字空间这个概念以前编译器用的是#include <iostream.h>, 而引入名字空间的概念以后std名字空间的头文件名字变成了<iostream>。 <...

if(a is b)print “a is b” 27.return:用于跳出函数,可以返回一个值也可以不返回值 28.def:用于定义方法 29.for:for….in 一起使用:遍历容器中的每个元素 30.lambda:即匿名函数,简化了函数定义的书写形式,使代码更为简洁,但是使用函数的定义方式更为直观,易理解。 下面两种写法是等价的。 例1: ...
